2021 Mercedes Actros 12.8L Diesel · GK21 AFZ

The most recent MOT test on February 10, 2026, confirms the vehicle remains roadworthy with no defects recorded at 672,208 miles. This consistency across all five annual tests—spanning February 2022 to February 2026—indicates no recurring mechanical failures or advisories. The absence of failings suggests either meticulous maintenance or a vehicle designed to tolerate high mileage without early component degradation. However, the lack of advisories in recent tests means critical wear items like suspension bushes, coil springs, or brake calipers were not flagged, though this does not preclude gradual deterioration over time. The mileage progression reveals an unusually aggressive usage pattern, averaging 134,442 miles annually—far exceeding typical commercial vehicle norms for this model’s age. Between February 2022 and February 2026, the vehicle accumulated 552,151 miles in just four years, with no gaps in testing. This rapid accumulation implies heavy operational demands, which may have accelerated wear on high-stress components such as drivetrain seals, transmission mounts, or exhaust manifolds. The consistent annual testing schedule further suggests the vehicle was kept in service without prolonged periods of inactivity, which could mitigate some corrosion risks but does not negate the need for proactive inspection of wear-and-tear items. Given the high mileage and commercial use, a buyer should prioritise an in-person inspection of the suspension system, particularly the rear axle bushes and coil springs, for signs of cracking or excessive play. The brakes, including rear binding calipers and front disc thickness, warrant scrutiny, as heavy braking cycles could have contributed to uneven wear. Structural integrity should be assessed for corrosion in wheel arches, subframe mounts, and exhaust underbody sections, especially if the vehicle operated in mixed conditions. While the MOT history shows no failings, the absence of advisories does not guarantee all components remain serviceable—critical items like differential seals, turbocharger condition, and hydraulic brake fluid contamination are not routinely tested and should be verified independently.
